变压吸附氯乙烯精馏尾气工艺改进

Improvements on process of pressure swing adsorbing tail gas from vinyl chloride rectification

介绍了变压吸附氯乙烯精馏尾气的工艺改进情况,改进后的工艺采用分路回收方法,实现了氯乙烯、乙炔和氢气的分别回收,该工艺运行平稳,可降低转化系统负荷,且氯乙烯和乙炔均达到了零排放,具有一定的经济效益和环境效益。

Improvements on process of pressure swing adsorbing tail gas from vinyl chloride rectification were proposed. In the improved process, components were recovered separately, reali- zing the separate recovery of vinyl chloride, acetylene and hydrogen. After improvement, the process operation was stable, the load of conversion system was reduced, and zero discharge of vinyl chloride and acetylene were accomplished, thus achieving better economic and environmental re- suits.
